Whether they have an intermediate step that is OCaml or not is irrelevant. Most compilers have one of more intermediate representations between source and executable. I think providing a syntax comparison to Javascript right next to a syntax comparison to OCaml is a clear indication that they are marketing to Javascript programmers, and the only reason for that is if they intend thelanguage as a replacement or supplement to Javascript.
That may or may not seem relevant to you based on ciniglio comment, but I think it's on point if you follow the thread from it's source down.
